Hong Kong has been left in shock after a night of violence on Sunday, which saw dozens of masked men storm a train station.
The men – dressed in white shirts and suspected to be triad gangsters – assaulted pro-democracy protesters and passers-by in the Yuen Long area.
This is the first time this kind of violence has been seen in the ongoing anti-extradition demonstrations.
Several lawmakers questioned why police were slow to arrive at the scene.
Footage posted on social media showed dozens of men attacking people with wooden rods and metal sticks inside the station.
Forty-five people were injured, with one person in critical condition.
Hong Kong’s Chief Executive Carrie Lam told reporters the gang attacks were “shocking”. She also condemned protesters for defacing China’s main representative office in the city earlier on Sunday.
